Abstract

The utility model discloses an inclined core-pulling structure in a mould, which comprises a rear template, a core-pulling fixed plate, a mould core and a core-pulling assembly; the core-pulling fixing plate is positioned below the rear template, the mold core is arranged in the rear template, and the core-pulling assembly comprises a core pulling part, a core-pulling sleeve and a slide rail seat; the bottom end of the core is fixed on the core-pulling fixing plate through a slide rail seat, the core-pulling sleeve is arranged in the mold core, and the core is upwards extended to sequentially pass through the rear mold plate and the core-pulling sleeve arranged in the mold core; when the mold is opened, the external driving mechanism drives the rear mold plate to move upwards, so that a distance exists between the rear mold plate and the core-pulling fixed plate, and the core pulling is completed.

Description

Inside structure of loosing core to one side of mould

Technical Field

The utility model belongs to the technical field of the mould, concretely relates to inside structure of loosing core to one side of mould.

Background

The plastic injection mold is a tool for producing plastic products and has wide application. In the injection molding of plastic products, core pulling is needed due to the internal structures of some plastic products, and most of the traditional core pulling mechanisms are complex in structure.

Therefore, a new technical solution is needed to solve the above technical problems.

SUMMERY OF THE UTILITY MODEL

Utility model purpose: for solving the problem that exists among the prior art, the utility model provides an inside oblique structure of loosing core of mould is applicable to the slope little, loose core apart from the short mould.

In order to solve the technical problem, the utility model provides an inclined core pulling structure inside a mould, which comprises a rear template, a core pulling fixed plate, a mould core and a core pulling assembly; the core-pulling fixing plate is positioned below the rear template, the mold core is arranged in the rear template, and the core-pulling assembly comprises a core pulling part, a core-pulling sleeve and a slide rail seat; the bottom end of the core is fixed on the core-pulling fixing plate through a slide rail seat, the core-pulling sleeve is arranged in the mold core, and the core is upwards extended to sequentially pass through the rear mold plate and the core-pulling sleeve arranged in the mold core; when the mold is opened, the external driving mechanism drives the rear mold plate to move upwards, so that a distance exists between the rear mold plate and the core-pulling fixed plate, and the core pulling is completed.

Furthermore, the core pulling obliquely upwards sequentially passes through the rear template and the core pulling sleeve arranged in the mold core.

Furthermore, the core pulling assembly also comprises a clamp spring, and the clamp spring is arranged in the mold core and is positioned below the core pulling sleeve; the upper end of the loose core extends upwards to sequentially penetrate through the rear template, the snap spring arranged in the mold core and the loose core sleeve.

Further, the external driving mechanism is an oil cylinder.

Has the advantages that: the utility model discloses an inside is loose core simple structure to one side, and the installation part is few and simple to operate, has advantages such as production cycle is short, realize that the process action is few, stability is high, product quality is stable.

Detailed Description

The invention is further explained below by reference to the drawings and examples.

As shown in fig. 1 to 4, the utility model discloses an inside oblique structure of loosing core of mould mainly includes: the core pulling device comprises a rear template 1, a core pulling fixing plate 2, a mold core 3, a core pulling 4, a core pulling sleeve 5, a clamp spring 6, a slide rail seat 7 and a screw 8; the core-pulling fixed plate 2 is positioned below the rear mold plate 1, and the core-pulling fixed plate 2 and the rear mold plate 1 are not directly connected, namely, under the action of external driving, a distance can be generated between the rear mold plate 1 and the core-pulling fixed plate 2; mould benevolence 3 sets up in back template 1, and the bottom of 4 of loosing core is passed through the screw fixation on slide rail seat 7 to fix at the fixed plate 2 of loosing core through slide rail seat 7, loose core cover 5 sets up in mould benevolence 3, jump ring 6 sets up in mould benevolence 3, and lies in the below of loose core cover 5, should loose core 3 upwards extend to one side and pass back template 1, set up jump ring 6 and the cover 5 of loosing core in mould benevolence 3 in proper order. When the mold is opened, the oil cylinder drives the rear mold plate 1 to move upwards, so that a distance exists between the rear mold plate and the core-pulling fixing plate, and at the moment, the core-pulling is separated from the product to generate core-pulling action.

The utility model discloses an installation step includes: firstly, installing the core-pulling sleeve 5 in the mold core 3, and then installing the clamp spring 6; installing the die core 3 into the rear template 1; installing a core-pulling fixing plate 2 with a rear template 1; mounting the loose core 4 on the slide rail seat 7; then the two are arranged in the die core 3 together; the slide rail seat 7 is locked on the core-pulling fixing plate 2 by a screw 8, and the installation is finished.
